BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 721,805, dated March 3, 1903. Application filed May 20, 1902. Serial No. 108,266. (No model.)

under sides with longitudinal grooves 16 to v To aZZ whom, it may concern:

Be it known that 1, CHARLES H. JACKSON, a citizen of the United States, residing at Bentonville, in the county of Benton and State of Arkansas, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to baling-presses; and its object is to provide a press adapted to be operated by hand-power which shall be simple in construction, compact, inexpensive, and sufficiently powerful to be practically useful for compressing hay and the like.

My invention consists in an improved construction, arrangement, and combination of the operating parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective View of a hand baling-press constructed in accordance with myinvention.

Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a detail sectional view perspective view of the sliding gate or griddle detached from the press.

Corresponding parts of the several figures are designated by like characters of referonce.

1 designates the press-box, which may be described as being composed of the sides 2 2, the bottom 3, and the permanent head or end piece 4. In addition to this the press-box is provided at its opposite end with the detachable end gate 5, which is provided with lugs 6, adapted to fit in sockets 7 provided for their reception in the ends of the side pieces 2 and where they are retained in position by means of pins or bolts 8.

9 designates the follower, with which the operating-screw 10 is connected by means of a swivel-joint 11. Said operating-screw extends through an opening 12 in the head 4 of the press-box, upon the inner side of which is mounted a nut or bushing 13, havinga threaded bearing for the said operating-screw. The latter is provided at its outer end with a crank 14, whereby it may be manipulated.

Suitably secured upon the sides of the press-box are cleats, (designated by 15,) one of said cleats being arranged on each side of the box. These cleats are provided in their receive the arms 17 of a yoke 18, which is thus adapted to slide longitudinally with relation to the press-box. The central part of the yoke 18 is provided with an opening or eye 19, affording a bearing for the outer end of the operating-screw 10, which is swiveled in said eye. It will be understood from this description that the operating-screw practically has a bearing and a support in the said yoke which when the press is in operation moves longitudinally with and is operated by the said screw.

20 designates a movable gate or griddle, which is composed of side pieces 21 and crossbars 22, connecting said sides. The latter are provided on their inner sides with laterally-extending lugs or tongues 22"-, adapted to engage recesses 23 in the outer sides of the follower 9. Mounted in recesses 23 in the inner sides of the side pieces 2 2 of the pressbox are the check-springs 24, adapted to engage the side bars of the griddle, as shown in Fig. 3.

In Figs. 1 and 2 of the drawings the movable gate or griddle has been shown in the position which it will occupy when a bale has just been compressedthat is, in engagement with the check-springs 24. The follower, however, has been partially withdrawn toward the head of the press-box in order that the construction may be more clearly seen and readily understood. To operate the invention, the follower 9 is Withdrawn until it nearly approaches the head 4 of the press-box. The gate 20 is placed adjacent thereto, with the lugs 22 engaging in the recesses 23. The detachable end gate 5 is also connected with the box, as shown in Figs. 1 and 2. The hay or other material to be com pressedis now thrown into the box, and when the latter is full the screw 10 is operated by means of its handle or clamp 14, thus forcing the follower 9 in the direction of the end gate 5 and compressing the contents of the box. When the checksprings 24 engage the movable gate 20, the bale will have been-sufficiently compressed and the follower may now be withdrawn while the bale is being tied, after which it may be ejected by removing the end gate 5.

The lugs 22 by engaging the recesses 23 in the follower perform an important function in keeping the gate or griddle steady during the operation of the press, and they have another function in that being attached to and projecting from the inner sides of the side pieces 21 of said gate they will serve to protect the ends of the check-springs 2& when the latter engage the side bars 21, as will be plainly seen in Fig. 1 of the drawings. The said lugs thus cooperate with the springs as well as with the follower, which latter is in no danger of being engaged or interfered with by said check-springs, the lugs 22 serving as guards for the points of said springs.

To the upper edges of the sides of the pressbox are secured cleats 25, the inner edges of which extend so as to overhang the press-box and to hold the follower 9, as well as the movable gate, securely therein during the operation of the press.

When the press is in operation,it will be seen that the weight of the screw when the latter is withdrawn from the press box is largely supported by' means of the sliding yoke, in which the outer end of said screw has a bearing. The screw being thus supported, the operation of the press is much facilitated, and undue strain upon the diiferent parts is avoided.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a baling-press, the combination of the press-box, the longitudinallymovable follower therein, the operating-screw swiveled to said follower and having its bearing in a nut or threaded bushing secured to the head of the box, grooved cleats secured to the sides of the box, and a yoke mounted slidingly in the said grooved cleats and having an eye or opening forming a bearing for the outer end of the operating-screw, substantially as set forth. 1

2. In a baling-press, the combination of the press-box, of the follower, the operating-screw and a support for the latter comprising a yoke having a bearingfor the outer end of the screw, and suitable supports in which the arms of said yoke are slidingly mounted, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES H. JACKSON.
